Description

Technical Field

[0001] The present application relates to the technical field of display panel testing, and in particular to a lighting test device, a lighting test method and related apparatus. Background Art

[0002] During the manufacturing process of the display panel, multiple inspection procedures need to be carried out, such as checking whether the pixels are good, checking whether the display panel is running normally, etc. These inspection procedures require lighting the display panel. The process of testing when the display panel is lit can generally be called lighting test.

[0003] At present, there is a one-to-one correspondence between the lighting test equipment and the model (or type) of the display panel. When the tester performs a lighting test on a certain model of display panel, it is necessary to use the lighting test equipment corresponding to the display panel of that model to perform the test. When the tester performs a lighting test on another model of display panel, it is necessary to use the lighting test equipment corresponding to the display panel of another signal. This process is rather cumbersome, and it is easy to use the wrong lighting test equipment when replacing the lighting test equipment. Summary of the invention

[0004] The present application provides a lighting test device, a lighting test method and related apparatus for improving the lighting test efficiency.

[0098] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0099] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0100] The application scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. It is known to those skilled in the art that with the emergence of new application scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems. In the description of the present application, unless otherwise specified, the meaning of "multiple" is two or more.

[0101] In order to simplify the process of testing personnel to perform lighting tests on display panels with different signals, the embodiments of the present application provide a lighting test device, a lighting test method and related devices. The specific implementation methods of the lighting test device, the lighting test method and related devices provided in the embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0102] Figure 1 An exemplary lighting test device is shown, which may include a panel connection module and a processing module.

[0103] The panel connection module is used to connect to the display panel to be tested. For ease of introduction, in the embodiment of the present application, the display panel connected to the panel connection module is recorded as the display panel to be tested. The display panel can be a display panel of any display device. The display device can include but is not limited to mobile phones, televisions, conference machines, all-in-one machines, smart notebooks, personal terminals and other devices.

[0104] The processing module can be used to detect the display panel type of the display panel to be tested, and perform a lighting test on the display panel to be tested according to a test instruction corresponding to the detected display panel type.

[0105] In some possible implementations, the processing module may pre-store a correspondence between the display panel type and the test instruction. Optionally, in the correspondence between the display panel type and the test instruction, the display panel type corresponds to one or more test instructions. For example, the test instructions corresponding to the display panel type 1 include test instruction a and test instruction b. The test instructions corresponding to the display panel type 2 include test instruction c, test instruction d, and test instruction f.

[0106] Any test instruction may include or carry parameters for displaying the display panel. Any test instruction may carry screen display parameters. Screen display parameters may include, but are not limited to, resolution, refresh rate, screen parameters (porch), and other parameters. If there are multiple test instructions corresponding to a display type, at least one different parameter exists in any two test instructions.

[0107] For ease of introduction, the display panel type of the display panel to be tested is recorded as the target type below. If the target type corresponds to multiple test instructions, the processing module can use any test instruction among the multiple test instructions corresponding to the target type to perform a lighting test on the display panel to be tested.

[0108] In a possible implementation, Figure 2 As shown, the lighting test device may further include a display device. The display device may display lighting test related content under the control of the processing module. The display device may be a display device based on a serial peripheral interface (Serial Peripheral Interface, SPI).

[0109] In some examples, the display device may display the test instructions corresponding to the target type so that the tester can know the test instructions corresponding to the display panel to be tested.

[0110] Optionally, the display device may display the identification of the test instruction corresponding to the display panel to be tested. The identification of the test instruction may represent the number of the test instruction and / or display the parameter status in the test instruction. This embodiment of the application does not specifically limit this.

[0111] In some examples, the processing module can execute preset application software to generate an image of a display interface of the display device. The image of the display interface can be used to display the identification of the test instruction corresponding to the aforementioned display panel to be tested, and / or to display the parameter status in the test instruction. Or the image of the display interface can be used to display information related to the lighting test. The processing module can be configured with an Android operating system, and the processing module can transmit the generated image of the display interface through the spi_dev node in the Android operating system, so that the display device displays the aforementioned generated image of the display interface.

[0112] In some examples, the display device includes a touch screen. The tester (ie, the user) can select a test instruction corresponding to the target type by touching the touch screen. The processor can perform a lighting test on the display panel to be tested according to the selected test instruction.

[0113] In other examples, such as Figure 3 As shown, the lighting test device may include an input device. The tester (i.e., the user) may select a test instruction from the test instructions corresponding to the target type by operating on the input device. The processor may perform a lighting test on the display panel to be tested according to the selected test instruction. Optionally, the input device may include an input button. Alternatively, the input device may include a knob. Alternatively, the input device may include a touch slider.

[0114] In a possible implementation, the panel connection module can support connecting multiple types of display panels. The panel connection module can cooperate with any of a plurality of pluggable adapter boards. The plurality of adapter boards correspond one to one with the plurality of display panel types. One adapter board corresponds to one display panel type, wherein one adapter board can only cooperate with a display panel of the corresponding display panel type. Each adapter board can be implemented as an adapter flexible printed circuit (FPC).

[0115] Figure 4A , multiple adapter plates that can be matched with the panel connection module are shown, which are multiple adapter plates in dashed boxes and one adapter plate in solid boxes. The panel connection module can be matched with any adapter plate in the dashed boxes and the adapter plates in solid boxes. The display panel to be tested is connected to the panel connection module only through one of the adapter plates, such as the adapter plate in the solid box is the adapter plate connected to the display panel to be tested in this example.

[0116] Each adapter board may include a coding circuit. For any adapter board, when the adapter board is connected to the display panel, the coding circuit in the adapter board may output a coding level corresponding to the adapter board to the processing module, wherein the coding level corresponding to the adapter board indicates the type of display panel corresponding to the adapter board.

[0117] The number of output terminals of the encoding circuits in different adapter boards is the same. An encoding circuit may include N output terminals arranged in sequence, where N is an integer greater than or equal to 2. The output terminals may be of two types, the first type of output terminal is recorded as a first output terminal, and the second type of output terminal is recorded as a second output terminal. The output level signal of the first output terminal is different from the output level signal of the second output terminal.

[0118] Optionally, the first output terminal outputs a level signal corresponding to a coding value of 0, and the second output terminal outputs a level signal corresponding to a coding value of 1. Alternatively, the first output terminal outputs a level signal corresponding to a coding value of 1, and the second output terminal outputs a level signal corresponding to a coding value of 0.

[0119] The following is an example in which the output level signal of the first output terminal is a level signal corresponding to the coding value 1 and the output level signal of the second output terminal is a level signal corresponding to the coding value 0.

[0120] The first output terminal is connected to the voltage level VCC through the first resistor unit, and the second output terminal is connected to the ground line through the second resistor unit. Optionally, if the encoding circuit includes multiple first output terminals, the multiple first output terminals can all be connected to the voltage level VCC through the same first resistor unit. Similarly, if the encoding circuit includes multiple second output terminals, the multiple second output terminals can be connected to the ground line through the same second resistor unit.

[0121] like Figure 4B As shown, the encoding circuit may include a first output terminal and a plurality of second output terminals, wherein the first output terminal is denoted as P1, and the plurality of second output terminals are denoted as M2 and M3 respectively.

[0122] The first output terminal P1 is connected to the level VCC through the first resistor unit, and the first output terminal P1 is not connected to the ground line. The second output terminal M2 is connected to the ground line through the second resistor unit. The second output terminal M3 is connected to the ground line through the second resistor unit. The level VCC can be configured to be greater than 0V. It can be seen that the level of the first output terminal P1 is greater than 0V, and the levels of the second output terminal M2 and the second output terminal M3 are equal to 0V.

[0123] Optionally, the equivalent resistance values ​​of the first resistance units in the encoding circuit may be the same or different, and the equivalent resistance values ​​of the second resistance units may be the same or different.

[0124] Optionally, the equivalent resistance value of the first resistance unit in the encoding circuit may be the same as or different from the equivalent resistance value of the second resistance unit.

[0125] It should be understood that the number of output terminals in the drawings involved in this example is only used for illustrative purposes and is not intended to be a specific limitation on the number of output terminals.

[0126] Among the N output terminals of the encoding circuits of different adapter boards, the number and order of the first output terminals and the number and order of the second output terminals are different. Figure 4B The three output terminals of the coding circuit shown in FIG. 1 are respectively the first output terminal P1, the second output terminal M2, and the second output terminal M3. The coding level output by the coding circuit can be 100. For example Figure 4C The three output terminals of the coding circuit shown in FIG. 1 are respectively the first output terminal P1, the first output terminal P2, and the first output terminal P3. The coding level output by the coding circuit can be 111.

[0127] In this example, the specific structure of the encoding circuit is only used as an example. It should be understood that various circuit structures that can realize the aforementioned encoding circuit outputting the encoding level can be applied to the present application.

[0128] From the above introduction, it can be known that among the N output terminals of the coding circuits of different adapter boards, the number and order of the first output terminals and the number and order of the second output terminals are different, so the output of the coding circuit in each adapter board can be used as the coding level of the adapter board. An adapter board can be connected to a display panel of a display panel type, so the coding level of the adapter board can represent the display panel type corresponding to the adapter board.

[0129] The processing module can pre-store the corresponding relationship between the encoding level and the display panel type corresponding to each display panel type, so that the processing module can determine the type of the connected display panel according to the output of the encoding circuit in the adapter board received, thereby realizing the detection of the display panel type of the display panel to be tested.

[0130] In one possible design, see again Figure 4D The processing module may include a processor. The processor has multiple general-purpose input / output (GPIO) interfaces. Some of the multiple GPIO interfaces can be connected to the output end of the encoding circuit in the adapter board connected to the panel connection module through the panel connection module, so as to receive the output level of the encoding circuit. The processor can obtain the corresponding relationship between each encoding level and the display panel type, or the processor can store the corresponding relationship between each encoding level and the display panel type.

[0131] Among them, a target adapter board among the multiple adapter boards is connected to the display panel to be tested, and the target adapter board outputs a target coding level to the processing module, and the target coding level is used to detect the display panel type of the display panel to be tested. The processor can be used to determine the display panel type corresponding to the target coding level as the display panel type of the display panel to be tested according to the correspondence between the preset coding level and the display panel type.

[0132] Through the above implementation, the lighting test device can automatically identify the display panel type of the connected display panel, thereby improving the lighting test efficiency.

[0133] In another possible implementation, the lighting test device may further include an instruction receiving module. In some examples, the instruction receiving module may include but is not limited to components such as buttons, knobs, and touch screens that receive user operations. For example, one display panel type corresponds to one button, and the processing module can detect the state of the button to detect the display panel type of the display panel to be tested. For another example, one display panel type corresponds to the rotation angle of a knob, and the processing module can detect the display panel type of the display panel to be tested by detecting the rotation angle of the knob. For another example, the touch screen can display a display panel list, and the user can select the display panel type of the display panel to be tested in the display panel list by touch. In some other examples, the instruction receiving module may include an audio acquisition circuit, and the audio acquisition circuit can collect the user's voice. The processing module identifies the type of display panel to be tested by voice recognition, and detects the display panel type of the display panel to be tested.

[0134] Optionally, the processing module may detect whether the display panel to be tested is abnormal. The processing module detecting whether the display panel to be tested is abnormal may include but is not limited to: detecting whether the power consumption data of the display panel to be tested is abnormal, detecting whether the temperature data of the display panel to be tested is abnormal.

[0135] In one possible implementation, Figure 5 As shown, the lighting test device may further include a collection circuit; the collection circuit is connected to at least one power supply circuit in the display panel to be tested, and is used to collect the voltage and current of the at least one power supply circuit.

[0136] In actual application scenarios, the display panel to be tested may include multiple power supply circuits, which are respectively used to power multiple columns or rows of pixels of the display panel to be tested. The acquisition circuit in the lighting test device can be connected to at least one power supply circuit of the display panel to be tested. Optionally, the acquisition circuit can be connected to each power supply circuit of the display panel to be tested. The acquisition circuit can collect the voltage and current of the connected power supply circuit, and output the voltage and current of each connected power supply circuit to the processing module. So that the processing module can determine the power consumption of each power supply circuit based on the voltage and current of each power supply circuit.

[0137] For some examples, see Figure 5 The acquisition circuit may include a microcontroller unit (MCU). The microcontroller unit may be used to connect the voltage and current of each power supply circuit of the display panel to be tested, and output the collected voltage and current of each power supply circuit to the processing module. The microcontroller unit may be connected to the processor in the processing module through a UART interface.

[0138] Optionally, the processing module can detect whether the power consumption data of the display panel to be tested is abnormal. When the power consumption data of the display panel to be tested is abnormal, the processing module can control the display panel to be tested to turn off the screen, such as powering off the display panel to be tested and stopping supplying power to the display panel to be tested, so as to turn off the display panel to be tested. In some examples, the processing module can determine whether the power consumption data of the display panel to be tested is greater than a power consumption threshold. If the power consumption data is greater than the power consumption threshold, it can be determined that the power consumption data is abnormal. If the power consumption data is less than or equal to the power consumption threshold, it can be determined that the power consumption data is normal.

[0139] Optional, such as Figure 5 As shown, the lighting test equipment may further include an abnormality warning light. When the processing module determines that the power consumption data of the display panel to be tested is abnormal, the abnormality warning light may be controlled to light up, thereby prompting the tester that the display panel to be tested is abnormal. Optionally, the lighting test equipment may further include a display device, and when the processing module determines that the power consumption data of the display panel to be tested is abnormal, the display device may be controlled to display power consumption abnormality prompt information. Optionally, the abnormality warning light may be implemented as an LED light.

[0140] The display panel is usually provided with a temperature sensor, which can detect the temperature of the display panel. In a possible implementation, the processing module can be connected to the display panel to be tested. The processing module can obtain the temperature data of the display panel to be tested from the display panel to be tested. For example, the processing module can read the temperature parameters stored in the register. Optionally, the processing module can be connected to the display panel to be tested through the Mobile Industry Processor Interface (MIPI) interface, and the processing module can obtain the temperature data of the display panel to be tested.

[0141] Optionally, the processing module can detect whether the temperature data of the display panel to be tested is abnormal. When the temperature data of the display panel to be tested is abnormal, the processing module can control the display panel to be tested to turn off the screen, such as powering off the display panel to be tested and stopping the power supply to the display panel to be tested, so as to turn off the screen of the display panel to be tested. When determining that the temperature data of the display panel to be tested is abnormal, the processing module can control the abnormality prompt light to light up, thereby prompting the tester that the display panel to be tested is abnormal.

[0142] In some examples, the processing module can determine whether the temperature data of the display panel to be tested is greater than a temperature threshold, and if the temperature data is greater than the temperature threshold, the temperature data can be determined to be abnormal. If the temperature data is less than or equal to the temperature threshold, the temperature data can be determined to be normal.

[0143] Optionally, the lighting test equipment may further include a display device, and when the processing module determines that the temperature data of the display panel to be tested is abnormal, the display device may be controlled to display temperature abnormality prompt information.

[0144] In a possible implementation, Figure 6 As shown, the lighting test device may further include a posture detection device; the posture detection device is used to detect the posture data of the display panel to be tested. The posture data of the display panel to be tested may include a deflection angle of the display panel to be tested and a preset direction. The preset direction may be a horizontal direction.

[0145] In some examples, the posture detection device is used to collect the state data of the display panel to be tested; the processing module can receive the state data provided by the posture detection device. The processing module is also used to determine the posture data of the display panel to be tested based on the state data. Such a design can detect whether the display panel to be tested is in a horizontal environment.

[0146] The lighting test equipment may further include a supporting mechanism for supporting the display panel. Optionally, the posture detection device may include a gyroscope, which may be used to collect status data of the supporting mechanism, and the status data of the supporting mechanism may be regarded as status data of the display panel to be tested. The status data of the supporting mechanism may include the angular velocity of the supporting mechanism in three axes, and the angular velocity of the three axes may include the roll angular velocity around the X-axis, the pitch angular velocity around the Y-axis, and the yaw angular velocity around the Z-axis. The processing module may determine the posture data of the supporting mechanism based on the status data, and the posture data of the supporting mechanism may be regarded as the posture data of the display panel to be tested.

[0147] In some other examples, the posture detection device may include a level, which is used to collect the inclination angle of the display panel to be tested and the preset direction. The lighting test equipment may also include a supporting mechanism for supporting the display panel. The level can collect the inclination angle of the supporting mechanism and the preset direction as the deflection angle of the display panel to be tested and the preset direction. Such a design can detect whether the display panel to be tested is in a horizontal environment.

[0148] The processing module can control the display device in the lighting test equipment to display the posture data of the display panel to be tested or to display whether the display panel to be tested is in a horizontal state, so as to prompt the tester whether the display panel to be tested is in a horizontal environment. The tester can adjust the posture of the bearing mechanism to change the posture data of the display panel to be tested.

[0149] In a possible implementation, Figure 7 As shown, the lighting test device may further include a device for obtaining a display panel connection status, wherein the device for obtaining a display panel connection status is connected to the processing module. The device for obtaining a display panel connection status can prevent the display panel to be tested from being plugged in or out while it is powered on.

[0150] When the device for obtaining the connection status of the display panel is in the first state, it can be indicated that the display panel to be tested is in a connection state with the panel connection module. At this time, the device for obtaining the connection status of the display panel outputs a first state indication signal to the processing module. The processing module powers on the display panel to be tested according to the first state indication information;

[0151] When the device for obtaining the display panel connection status is in the second state, it can indicate that the tester is ready to disconnect the display panel to be tested from the panel connection module. At this time, the device for obtaining the display panel connection stops outputting the first state indication signal to the processing module. The processing module powers off the display panel to be tested according to the failure to receive the first state indication signal. Alternatively, the device for obtaining the display panel connection outputs the second state indication signal to the processing module, and the processing module powers off the display panel to be tested according to the second state indication signal.

[0152] In some examples, the device for obtaining the connection status of the display panel may include a switch circuit, and the output end of the switch circuit may be connected to the processor in the processing module, for example, the output end of the switch circuit may be connected to the GPIO interface of the processor. The voltage output by the output end of the switch circuit may be used as the key value of the switch circuit. Among them, when the output end of the switch circuit outputs a first voltage, that is, outputs a first state indication signal, the key value of the switch circuit is the first key value. When the output end of the switch circuit stops outputting a voltage or outputs a second voltage, that is, outputs a second state indication signal, the key value of the switch circuit is the second key value. The processor can monitor the key value of the GPIO interface to monitor whether the first state indication signal is received.

[0153] Optionally, when the switch in the switch circuit is in a closed state, the output end of the switch circuit outputs a first state indication signal. When the switch in the switch circuit is in a short circuit state, the output end of the switch circuit outputs a second state indication signal.

[0154] The state of the switch in the switch circuit is changed by the operation of the tester. The switch circuit may include a circuit part and a mechanical structure. The operation of the mechanical structure by the tester may change the state of the switch in the switch circuit. After the display panel to be tested is connected to the panel connection module, a first operation needs to be performed on the mechanical structure to make the switch in the switch circuit closed. The tester needs to perform a second operation on the mechanical structure before the connection between the display panel to be tested and the panel connection module can be disconnected.

[0155] based on Figure 7 The structure of the lighting test equipment is shown. Fig. 8A The functional schematic diagram of a lighting test device is shown as an example. After the lighting test device is powered on, at least one initialization task can be executed.

[0156] At least one initialization task may include: initializing a serial port connected to an acquisition circuit, initializing a device for acquiring a display panel connection status, initializing a display device, and initializing a posture detection device.

[0157] The processing module can receive voltage and current parameters through the serial port connected to the acquisition circuit. After controlling the display panel to be tested to light up, the processing module can read the voltage and current of the power supply circuit in the display panel to be tested through the serial port connected to the acquisition circuit, so as to obtain the power consumption data of the display panel to be tested. When determining that the power consumption data is abnormal, the processing module can switch the state of the abnormality indicator, such as switching the abnormality indicator to a lit state.

[0158] Optionally, the processing module may receive temperature data of the display panel to be tested, and when determining that the temperature data is abnormal, switch the state of the abnormality indication light, such as switching the state of the abnormality indication light to a lit state.

[0159] After the lighting test equipment initializes the device for obtaining the connection status of the display panel, the processing module can monitor the first status indication signal output by the device for obtaining the connection status of the display panel. In response to detecting the first status indication signal, the processing module can control the display panel to be tested to light up the screen.

[0160] The processing module can control the display device to display lists, data, images and other contents related to the test.

[0161] After the lighting test equipment initializes the posture detection device, the processing module can obtain the posture data of the display panel to be tested based on the data provided by the posture detection device.

[0162] In one possible implementation, Figure 8B The functional schematic diagram of a lighting test device is shown as an example. After determining that the power consumption data or temperature data is abnormal, the processing module performs a screen-off operation, switches the state of the abnormal prompt light, and controls the display device to display prompt information.

[0163] In addition, the embodiment of the present application may also provide a lighting test method, which may be applied to the lighting test device provided in any of the above embodiments. The method may be executed by a processing module, for example, by a processor in the processing module. Fig. 9 As shown, the method may include the following steps:

[0164] S901, detecting a first display panel type of a first display panel to be tested that is connected.

[0165] In specific implementation, since the lighting test equipment can support multiple types of display panels, after the lighting test equipment performs a lighting test on the current display panel, the tester can replace the display panel, and the lighting test equipment can detect the display panel type of the replaced display panel.

[0166] In a possible application scenario, in a scenario where a lighting test device performs lighting tests on two display panels in sequence, for easy distinction, the display panel tested first by the lighting test device is recorded as the first display panel to be tested, and the display panel tested later is recorded as the second display panel to be tested. The first display panel to be tested can be any type of display panel.

[0167] The processor may detect the display panel type of the connected display panel to be tested. The specific detection process may refer to the relevant introduction in the aforementioned embodiment, which will not be described in detail here.

[0168] S902, determining a test instruction corresponding to the first display panel type;

[0169] In a specific implementation, the processor may obtain the correspondence between the display panel type and the test instruction in advance, and determine the test instruction corresponding to the first display panel type. The number of the test instructions corresponding to the first display panel type may be one or more.

[0170] In some examples, the processor kernel supports the Android system. The processor may store a file including the correspondence between the display panel type and the test instruction. The processor can query the test instruction corresponding to any display panel type from the file. Any test instruction may include or carry parameters for displaying the display panel. Any test instruction may carry screen display parameters. The screen display parameters may include but are not limited to parameters such as resolution, refresh rate, and screen parameters. If there are multiple test instructions corresponding to a display type, at least one different parameter exists in any two test instructions.

[0171] The processor may obtain a test instruction selected by the tester from the test instructions corresponding to the first display panel type, and record it as the first test instruction.

[0172] S903: Control the first display panel to be tested to light up the screen according to the test instruction corresponding to the first display panel type.

[0173] In specific implementation, the processor may control the first display panel to light up based on the screen display parameters carried by the first test instruction. For example, the processor may control the first display panel to light up by controlling the first display panel to power on.

[0174] In a possible implementation, in response to detecting the first state indication signal, the processor may execute step S901, that is, detecting the first display panel type of the connected first display panel to be tested.

[0175] The processor may control the first display panel to be tested to turn off the screen in response to not detecting the first state indication signal. The processor not detecting the first state indication signal may reflect that the tester is ready to replace the display panel, so the processor controls the first display panel to be tested to turn off the screen to prevent the first display panel to be tested from being damaged when the screen is turned on and replaced.

[0176] In a possible implementation, the processor controls the first display panel to be tested to light up the screen through the display system of the Android operating system.

[0177] If the first display panel to be tested is the first display panel connected after the lighting test device is turned on, the kernel of the processor executes a first test instruction for the first display panel to be tested, and the screen display parameters carried by the first test instruction may be stored in the compiled firmware.

[0178] When the display subsystem (display) of the Android operating system is initialized, the screen display parameters in the first test instruction of the first display panel to be tested can be obtained. The hardware synthesizer (HWC) in the Android operating system is used to control the first display panel to be tested to light up the screen based on the screen display parameters in the target test instruction of the first display panel to be tested.

[0179] It can be seen that the processor can control the first display panel to be tested to light up the screen by utilizing the system layer of the Android operating system in the above manner.

[0180] The following is an introduction to the process of the processor controlling the first display panel to be tested to turn off the screen. Generally speaking, a screen-off method is provided in the Android operating system, and the screen-off method is triggered and called when a standby event occurs in the Android operating system. Since the lighting test equipment provided in the embodiment of the present application needs to be in operation while controlling the first display panel to be tested to turn off the screen, standby time cannot be generated. In the embodiment of the present application, by adding a screen-off call interface to the system layer of the Android operating system, the processor can execute the aforementioned screen-off method through the screen-off call interface to control the display panel to be tested to turn off the screen. In some examples, the screen-off call interface can be set in the service surfaceflinger of the display system.

[0181] After the processor controls the first display panel to be tested to turn off the screen, the processor can continue to monitor the first state indication signal, and if the first state indication signal is detected, the display panel type of the second display panel to be tested is detected. For ease of introduction, the display panel type of the second display panel to be tested is recorded as the second display panel type. If the second display panel type is the same as the first display panel type, the second display panel to be tested can be controlled to turn on the screen based on the target test instruction of the first display panel to be tested.

[0182] If the second display panel type is different from the first display panel type, the processor controls the second display panel to be tested to light up the screen according to the test instruction corresponding to the second display panel type. The processor can obtain a test instruction selected by the tester from the test instructions corresponding to the second display panel type, and record it as the second test instruction.

[0183] The processor can control the second display panel to be tested to light up the screen based on the second test instruction. After the Android operating system is started, the display subsystem (display) only performs the initialization process once. Therefore, the screen display parameters obtained when the display subsystem is initialized at this time are the screen display parameters in the first test instruction of the first display panel to be tested, and cannot be applied to the lighting test of the second display panel to be tested. Therefore, the processor needs to update the screen display parameters already obtained by the display subsystem to the screen display parameters carried in the second test instruction.

[0184] The processor may control the display subsystem to be initialized again so that the display subsystem can re-acquire the screen display parameters. Optionally, the processor may restart the Android operating system so that the display subsystem in the Android operating system can be initialized again so as to acquire the screen display parameters in the second test instruction. Alternatively, the processor may restart the display subsystem so that the display subsystem is initialized again so as to acquire the screen display parameters in the second test instruction.

[0185] Restarting the Android operating system takes a long time, which affects the efficiency of the lighting test. To improve the efficiency of the lighting test, the processor can restart the display subsystem. Among them, the processor can search for the process identifier of the HWC in the Android operating system. Exemplarily, the processor can call a preset search interface for searching the process identifier of the HWC and execute a method for searching the process identifier of the HWC. Optionally, the search interface can be set in the service surfaceflinger of the display system.

[0186] The processor can terminate (kill) the process according to the process identifier of the HWC, so that the display subsystem of the Android operating system is restarted. Among them, the display subsystem of the Android operating system is initialized again, and the screen display parameters in the second test instruction of the second display panel to be tested can be obtained. The HWC in the Android operating system is used to control the second display panel to be tested to light up the screen based on the screen display parameters of the second test instruction of the second display panel to be tested.

[0187] In a possible implementation manner, after the processor controls the first display panel to be tested to light up, the following operations may be performed:

[0188] Detecting whether the first display panel to be tested is abnormal;

[0189] After detecting that the first display panel to be tested is abnormal, the first display panel to be tested is controlled to turn off the screen.

[0190] In some examples, the processor may perform the following steps in the operation of detecting whether the first display panel to be tested is abnormal:

[0191] Receive the power supply voltage and current of the first display panel to be tested, and detect whether there is power consumption abnormality based on the power supply voltage and current; and / or receive the temperature parameters of the first display panel to be tested; and detect whether there is temperature abnormality based on the temperature parameters.

[0192] The processor may control the first display panel to be tested to turn off the screen when abnormal power consumption is detected, and may control the first display panel to be tested to turn off the screen when abnormal temperature is detected.

[0193] Based on the above introduction, Fig.10 An exemplary lighting test method is shown, which may include the following steps:

[0194] S1001: Obtain a third display panel type of a third display panel to be tested that is currently connected.

[0195] In a specific implementation, the processor can determine that the lighting test device is connected to the display panel to be tested according to the detection of the first state indication signal. The display panel to be tested is connected to the lighting test device through a corresponding adapter board, and the adapter board can output a coding level corresponding to the adapter board. The coding level corresponding to the adapter board represents the display panel type of the display panel corresponding to the adapter board.

[0196] The processor may determine the display panel type of the third display panel to be tested that is currently connected according to the correspondence between the preset coding level and the display panel type and the received coding level, which is recorded as the third display panel type.

[0197] The first state indication signal can indicate that the lighting test device is currently connected to the display panel to be tested. The device for obtaining the display panel connection state can output the first state indication signal to the processor. The specific method can refer to the relevant introduction in the above embodiment, which will not be repeated here.

[0198] S1002, determining whether the third display panel type is the same as the fourth display panel type, if so, executing step S1003 as the next step, if not, executing step S1004 as the next step.

[0199] During specific implementation, the fourth display panel type is the display panel type of the fourth display panel to be tested that was previously connected to the lighting test equipment.

[0200] S1003, executing the test instruction determined last time, and controlling the third display panel to be tested to light up the screen.

[0201] In specific implementation, since the display panel type of the third display panel to be tested connected this time is the same as the fourth display panel type of the display panel connected last time, the lighting test device can continue to perform the test using the test instruction corresponding to the display panel connected last time.

[0202] Since the parameters of the display panel in the processor kernel are the parameters of the display panel in the test instructions corresponding to the display panel connected last time, the lighting test of the third display panel to be tested can continue to use the test instructions corresponding to the display panel connected last time. The processor may not restart the display subsystem in the Android operating system. The processor may directly use the surfaceflinger service of the display subsystem in the Android operating system to control the third display panel to be tested to light up.

[0203] S1004: Obtain a target test instruction for a third display panel to be tested.

[0204] In specific implementation, the tester can select a test instruction for the third display panel to be tested by lighting the display device and / or the input device of the test device, and record it as the target test instruction. The processor can update the parameters of the display panel in the target test instruction to the Android operating system kernel.

[0205] S1005, restart the display subsystem.

[0206] In a specific implementation, after the display subsystem is restarted, the display subsystem obtains the screen display parameters in the target test instruction of the target display panel to be tested during initialization.

[0207] S1006, executing the target test instruction to control the third display panel to be tested to light up the screen.

[0208] In a specific implementation, the display subsystem may control the target display panel to be tested to light up the screen according to the screen display parameters in the target test instruction obtained from the target display panel to be tested.

[0209] S1007, when it is detected that the third display panel to be tested is abnormal, control the third display panel to be tested to turn off the screen.

[0210] In specific implementation, the processor may determine that the third display panel to be tested is abnormal when detecting that the power consumption data of the third display panel to be tested is abnormal. Alternatively, the processor may determine that the third display panel to be tested is abnormal when detecting that the temperature data of the third display panel to be tested is abnormal.
